Suppression of a signal reflected from the underlying surface is being performed for the cause of location of the low-lying objects. Since the spectral characteristics of the signal and noise match, spatial difference is formed by oblique irradiation. Spatial differences are allocated by the radiation pattern. The suppression is performed by forming the zero value in the equivalent radiation pattern. The equivalent radiation pattern is a section of a generalized ambiguity function of the signals. The graphs of equivalent diagrams are shown for several areas of suppression in the view sector. The adaptive system is performing the equivalent radiation pattern zero-value scan of the underlying surface in the view sector. These algorithms are successfully applied to the MIMO system. A feature of the MIMO system is spotted in the task of forming zero values of the equivalent radiation pattern.

Modern trends in the transformation of business structures and forms of inter-firm cooperation have led to the emergence of new organizational and structural solutions allowing businesses to successfully compete in the market, respond quickly to changes in the external environment and internal changes, contributing to the development potential of the business. So in the Russian economic practice, along with established corporate organizational structures and network business structures brand new specific structural forms are gaining popularity, being diversified entrepreneurial business systems, combining features of corporate and network structures, but also having specific characteristics that allow them to be identified as an independent type of structures. This paper discusses the most important parameters influencing the development of a diversified network of entrepreneurial business systems and analyses key characteristics of the data structures to identify their place in the chain of organizational structures evolution

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).

The article investigates the impact on the normal stresses of inequality of the young modulus for tension and compression in the bending of reinforced beams. Obtained formulas for determination of the bending moments that arise in the fixture, compressed and stretched zone of the aggregate. Found the formula for the normal stresses arbitrarily supported reinforced beams, arbitrary cross section and arbitrarily loaded bending loads. For example, reinforced beams of rectangular cross-section shows the determination of the neutral line and maximum stresses.

In presented article rank criteria for the statistical analysis of two selections are considered. These criteria check statistical hypotheses. Three groups of rank criteria were considered: about equality of the central tendencies, scopes of a variation and distribution laws. Researches were conducted on data on exchange rates in two next days in nine banks. Correctness of criteria was estimated proceeding from an US dollar exchange rate established by the Central bank of Russia. To these data rank criteria of Wilcoxon, Van der Waerden, Kolmogorov-Smirnov and others were applied rubbed. Coinciding values of two selections were estimated by means of a method of an average rank. For all examples rank criteria gave the correct assumptions of equality of two selections.

The article deals with the analysis of the application of the method of NS. Strelets for the static calculation of construction structures. It is proposed on the basis of the probabilistic-statistical method NS. Streletsky instead of the normal laws for operating voltages and strength apply laws with a shift, in particular, the law of the Weibull with three parameters and the Fisher-Тippet. It is proposed to make the transition to the parameters of the totality of the finite volume that will allow to increase the accuracy of calculation of probability of failure-free operation and the proposed probabilistic safety, and also to optimize the probability of trouble-free operation of construction structures
